CD5731 Schematic

CD5731 Features

Total Ionizing Dose Tested to 30 Krad(si)

Displacement Damage Tested to 3 MEV x 10¹²

1,500VDC Withstand Test Voltage

8-pin DIP Package

Low Input Requirement of 0.5mA

High Current Ratio (Typically 1000%)

Hermetically Sealed


This devices is a dual channel, hermetically sealed optically coupled isolator.  Each channel is composed of a Gallium Arsenide infrared emitting diode and a high gain photon detector.  The high gain output stage features and open collector output providing both lower output saturation and higher speed of operation than is possible with conventional photo-darlington type couplers.

The CD5731 series are being used in harsh radiation environments encountered by space applications. Package styles for this device include an 8-pin DIP package, with surface mount and solder dip options available.  These packages have a shield effect to cut off ambient light as they are designed for high density mounting applications.

Absolute maximum ratings, recommended operating conditions, electrical specifications and performance characteristics are identical for all units. Any exceptions, due to packaging variations and limitations, are as noted in the datasheet.
